26.3.2.4. Size

These options define the size and width of the memory.
  • S1 Data Width—This setting determines the data width of the memory. The available choices are 8, 16, 32, 64, 128, 256, 512, or 1024 bits. Assign Data Width to match the width of the host that frequently accesses this memory or has the most critical throughput requirements. For example, if you are connecting the On-Chip Memory II to the data host of a Nios® V processor, you should set the data width of the On-Chip Memory II to 32 bits, the same as the data-width of the Nios® V data host. Otherwise, the access latency could be longer than one cycle because the Avalon® interconnect fabric performs width translation.
  • S1 AXI Transaction ID Width—This setting determines the width of the AXI Transaction ID.
  • Total memory size26—This setting determines the total size of the On-Chip Memory II block. The total memory size must be less than the available memory of the target FPGA.
26 The memory size is automatically rounded up to a power of 2 by IP during instantiation to match the AXI address span.
